El Paular, the first monastery in Castile, was founded in 1390 on the orders of John I of Spain. The site underwent a constant process of evolution at the hands of architects Juan Guas, Rodrigo Gil de Hontañón, Francisco Hurtado and Vicente Acero. The church conserves its Flamboyant Gothic façade, and has a nave with a polygonal apse. The cloister is notable for its austerity and its ogive vaulted ceilings, and is surrounded by the friars’ cells. After the sale of church lands, the monastery was abandoned, but was restored its original use in 1910.
